To nii/'Z whom, t may concern,.-

Be it known that we, JOHN M. BROWNING and Marrana' S. Bnownine, of Ogden, in the county of Weber and Territory of Utah, have invented a new Improvement-in Magazine- Guns; and we do hereby decla-re the following,

wh en taken in connection with accoinpanyin g drawings and the letters of reference marked' thereon, to be a full, clear, and exact description of the same, and which said drawings con- Figure l, a side view of a re-arin-with the invention applied; Fig, a longitudinal sectien ci the muzzle-end portion of the barrel with the invention applied; Fig. 3.a front end view ci the same; Fig. 4, a modieation.,

This invention relates to a'n improvement in the construction of guns whereby the firing ef the gun afterthe first -discharge may be made automatic so long as cartridges shall be supplied.

The invention is applicable to machine-guns and also' te tire-arms. The invention is designed to gases generated in the discharge as a means for cpening the breech, cooking .the hammer, rejecting the cartridgeshell, introducing a new cartridge, and then reclosing the breech, and inl such reclosing to release the hammer for the discharge ci the cartridge so introduced, successive cartridges following each other in the diseharge'sa long as the supply is maintained; and it consists gin the construction and combination of rnehanism, as hereinafter' described, and particularly recited in the claim; In iiiustrating the invention we show it as applied to a rearrn. e El :esente the stock; B, the barrel; C, the

- magasine; E, t'iie'receiver, within which is the breech mechanism of the arm. This mechanistn may be any of the many known constructions whereby the breech-piece is opened,

the nain nier cocked, the cartridge transferred fremthe magazine to a position forward of.

the hreechepiece, and so that thereturn'of the breech-piece will 'force the cartridge into the barrel. This mechanism is not shown, it be toe weil known te require illustration.

E reprcsers a lever, which is hung Upon a pivot F in the receiver and by the backward employ thev and forward swinging movexnentot vwhich the breechfincchanism is operated in the usual manner. This lever maybe understood as the usual trigger-gua-rd7 lever, by the forward movement of which, as in broken lines, the breech-piece isl thrown tothe open position anden the return the breech-piece lis closed.-

G represents a cap arranged over the 'forward or rnuzzle,A end of the barrel.v 4This cap has through its center and normally in line with the barrel an opening H, through which the bullet will freely pass.- The cap is best concave upon the inside, and'so as to present toward the barrel an area substantially as large vas the area of the 'end of the barrel.` The 'concave shape forms a chamber between the end 'o'the'barrel and the cap, so as to expose the large area of the cap to thebore of the barrel. In the preferred arrangement this cap is formed as a part vof a lever I, 'hung upon va 'fulcrum J- to anarm K, vwhich extends down from the forward ond of the barrel, and so 'that the capmay swing on the pivot J in a vertical plane, as from the position seen in Fig. l to that seen in broken lines, same figure.-l

extending forward, its other end is` hung to the cap-lever I, so as to make connection between the said lever and the operating-lever. A spring, as M,

is provided, the tendency ofwhich is to force andyieldingly hold the cap in its closed position. This spring, as here represented, is a dat spring secured by one end to the arm K,

and, extending downward, bears upon an extension or short arm N ofthe lever-I below the pivot, and so that this arn'i N of the lever opfv crates as a cam'againstthe springto compress the spring when -the cap is thrown open, as seen inbroken linesfFig. 1,-and then the-rcaction of the spring will return the capi' G represents the trigger, whichy is adapted to be pulled by hand in the usual manner, butv vextends intoapos'ition in rear of or so' as to stand in thepathof movement'ofthe lever E, and so that as the lever treme rear positiomasseen in Fig. 1, it will bear upon the trigger 0,"so as to impart a plates the construction. i

In using thc gun the magazine 4is charged L represents a connecting-rod,which is hung l 'by one end tothe lever E, and,

E approaches its 'exf pulling movement to the trigger, This com` 'm in the usual manner and the operating-lever yE moved by hand to introduce therst can. tridge into th'ebarreh. Then the triggeris.- pulled to discharge that-first cartridge.,4 Upon the discharge o f v that cartridge' "the'ibullet `passes out through 'the' opening. lH--iny the cap G. The gases immediately-,following operate upon the large inner 's fnrface of the cap-G, with a force sufficient to .throw the cap away from the end of the barrel, as represented inI broken lines, Fig. 1, and against the powerof the spring M y This movement ofthe cap draws the operating-lever E forward, as also seen in broken lines, Fig-1, and'produces'the open-'- 'ing movementl of the breech-piece and cocks 1the hammer; but instantly the spring M re# acts and forces the cap back to its "closed pof' sition, returning the operating-lever Efwhereby the second cartridge'is inserted into the barrel, the breech-piece closed,and as .the le= verE completes its rear movement it strikes the trig erand discharges the hammer, wh`ere-l upon that second cartridge is fired with the' same result as the first. Thus after the tirrv ing of thefirst cartridge b'yhand subsequent 'as a supplyis maintained.

cartridges will-be red automatically so lang .l We claim-- breech, anduhavin'g mechanism for .opening "anopening thro'ngh 'it in dinewithjthe-b'ore 35l of .the barrel andl.,throgh Whih the bullet l may pass, .the cap preser'iting.y `upon inner :j l surface an area larger than the bore offthel.
